If we're a input-only remote desktop session, create libei regions on an
absolute pointer device corresponding to all logical monitors. This
allows absolute pointer motions without screen casting.

Sometimes it makes no sense to have a shared pointer device, for example
when they have no set region occupying the global stage coordinate
space. This applies to for example window screen cast based pointer
device regions - they are always local to the window, and have no
position.
We do need shared absolute devices in some cases though, primarily
multi-head remote desktop, where it must be possible to keep a button
reliably pressed when crossing monitors that have their own
corresponding regions.
To handle this, outsource all this policy to the one who drives the
emulated input devices. Remote desktop sessions where the screen casts
correspond to specific monitors (physical or virtual), we need to make
sure they map to the stage coordinate space, while for window screencast
or area screencasts, we create standalone absolute pointer devices with
a single region each.

How EIS will be used depends on its context, meaning we'll have multiple
EIS contexts that expose different things. To prepare for this remove
the global socket since that won't work with multiple contexts.
